more particularly to buckets of that character commonly used inconnection with driven or pipe wells.

The invention has for its object the provision of a well bucketconstructed from a single sheet of metal, and means for. retaining theedges of the metal sheet in looking:

engagement, said retaining means also providing reinforcements for thebucket to space the body thereof from the well pipe.

A further object of the invention resides in the provision of a wellbucket formed from a single sheet of metal provided upon itslongitudinal edges with interlocking tongues, the ends of the bucketbeing conically formed and corrugated, the body of said bucket havingannular grooves formed therein, and retaining rings seated in saidgrooves to hold the edges of the metal sheet in interlocking engagementwith said rings and projecting beyond the periphery of the bucket bodyto prevent wear thereon.

With the above and other objects in view, the invention consists of thenovel features of construction, combination and arrangement of partshereinafter fully described and claimed, and illustrated in theaccompanying drawings, in which Figure 1 is a perspective view of a wellbucket constructed in accordance with the present invention; Fig. 2 is adetail longitudinal section of one end of the bucket; and Fig. 3 is asection taken on the line 3-3 of Fig. 1.

Referring in detail to the drawing 5 designates a sheet metal plate ofsuitable length and width from which my improved bucket is formed. Thissheet metal plate on each of its longitudinal edges is provided with thereversely disposed tongues 6 which are adapted for interlockingengagement. The sheet metal plate is further provided adjacent to eachof its ends with a substantially semicircular groove 7 which, when-theedges of the sheet are connected provides annular grooves in which areseated the reinforcing rings 8. The interlocked longitudinal edges ofthe body plate are then hammered to closely unite the same and preventtheir separation. The rings8 are of sufiicient diameter to completelyfill the annular groove 7 and project beyond the periphery of the bodyof the bucket as shown in Fig. 1. The ends of the bucket beyond thereinforcing rings 8 are contracted or of cone-shaped form as indicatedat 9. These conical ends of the bucket are crimped or corrugated as at10 whereby the ends of the bucket are materi-. ally strengthened. To oneof the conical ends 9 of the bucket, a suitable bail 11 is rigidlysecured, and to this bail the means are connected whereby the bucket israised and lowered in the well. In the other conical end of the bucket,a bucket valve of any approved construction is arranged.

From the above it will be seen that my improved bucket may beinexpensively constructed from a single sheet of 'metal and by providingthe rings 8 at opposite ends of the bucket body, a very rigid anddurable construction is obtained. These rings which project beyond theperiphery of the body engage the walls of the well pipe and space SerialNo. 629,786.

the body of the bucket therefrom so that wear thereon is entirelyeliminated. When the rings 8 are worn down to the periphery of thebucket, they may be readily removed and replaced by others, thusindefinitely prolonging the period of usefulness of the bucket. The seam6 of the bucket is of course, first opened sufiiciently so that therings may be forced over the ends of the bucket and into the grooves 7.It will be obvious, that as the rings may be obtained in largequantities at an insignificant cost, the expense incident to the repairof the bucket is negligible. These rings further serve to overcome allliability of disengagement of the connected edges of the sheet metalplate from which the bucket is formed, and relieve the interlockinglongitudinal tongues 6 of undue strain which might cause the same tobend and separate. In the usual construction of well buckets, theconical ends 9 are separately formed and riveted or otherwise secured tothe ends of the bucket body. It frequently happens, that after anextended period of use, the rivets are unable to withstand the strainsplaced thereon and break, whereupon the bucket falls to the bottom ofthe Well from which position considerable difliculty is experienced inremoving the same.

From the foregoing it is thought that the construction and manner ofassembling my improved bucket Will be readily understood.

The device is extremely simple, highly efficient in use and provides avery light, strong and durable bucket construction, wherein the manydeficiencies existing in devices of this class as heretofore constructedare entirely obviated.

\Vhile I have shown and described the preferred construction andarrangement of the various parts, it Will be understood that the deviceis susceptible of considerable modification Without departing from theessential feature or sacrificing any of the ad vantages thereof.

Having thus described the invention What is claimed is 1. A Well bucketconsisting of a cylindrical body having conical corrugated end portions,said body having an annular groove at the inner end of each of theconical portions thereof, and metal reinforcing rings seated in saidgrooves and projecting beyond the periphery of the bucket.

2. A Well bucket consisting of a single sheet of metal havinginterlocking means formed upon its longitudinal edges, the ends of saidbucket being conically formed and provided With annular grooves at thejuncture of said conical end portions With the body of the bucket, andreinforcing rings of circular form in cross section seated in saidgrooves, said grooves being of a depth sufficient to receivesubstantially one-half of the rings, said rings projecting beyond theperiphery of the body of the bucket, substantially as and for thepurpose specified.

In testimony whereof I hereunto aflix my signature in the presence oftwo Witnesses.
